4 Claims.

This invention relates to an attachment for tractors, and more particularly to such an attachment adapted for the driving of posts, piles or the like.

A primary object of this invention is the provision of an improved attachment for tractors adapted to be utilized as a post or pile driver, and adapted to reduce to a minimum the time and effort required to set such articles, as for example, fence posts or the like.

An additional object .of the invention is the provision of such a device which may be readily attached to any tractor embodying a power lift and operated thereby with a minimum of difficulty and power loss.

Another object of the invention is the provision of such a device provided with improved guide means, whereby the post or pile may be readily aligned under the driving block and readily positioned for driving the same. A still further object of the invention resides in the provision of such a device which may be simply and economically attached to any existing tractor provided with a power lift operated thereby.

Further objects reside in the provision of such a device which will be sturdy and durable in construction, reliable and efflcient in operation, and adapted to be constructed of a comparative minimum of operating parts.

Other objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out hereinafter and disclosed in the accompanying drawings, wherein there is shown a preferred embodiment of this inventive concept.

In the drawings:

Figure l is a rear elevational view of one form of device embodyin this inventive concept, shown in association with a tractor;

Figure 2 is a sectional view taken substantially along the line 2--2 of Figure l as viewed in the direction indicated by the arrows.

Figure 3 is a top plan view of the device shown in Figures 1 and 2.

Figure 4 is a fragmentary perspective view of a. constructional detail.

Figure 5 is a fragmentary perspective view of the driving block comprising a portion'of the mechanism and its associated guide means.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Having reference now to the drawings, there is generally indicated at III a fragment of a conventional tractor including a-rear axle II and rear driving wheels I2 provided with tires I3. The tractor is provided with a conventional power lifting device I4 including lift arms I5, attached to a shaft I5, and so arranged that rotation of the shaft will impart oscillatory motion to arms l5.

The attachment of the instant invention comprises a pair of horizontally extending arms I6 secured, as by bolts ll, to the tractor frame Ill. The arms l6 terminate in guide rods l9 secured at their extremities, as by means of rivets 29, which guide rods extend upwardly vertically and terminate in inwardly turned portions 21 forming a journal 22 within which is rotatably, mounted, as on anaxle 23, a pulley 24. Angularly disposed reinforcing members 25 are fixedly secured to the upper extremities ofthe-guide rods I9 and extend to form looped, relatively resilient portions 21, the extremities of which are secured, as by bolts 28, to the tractor frame. Auxiliary reinforcing members 29 are secured, as by bolts 30, to flanges 3| of rings 32 adapted to surround the axle 12 at spaced points adjacentthe extremity thereof, and extend to intermediate portions of members 25 to which they are secured, as by rivets 29. h

A driving block 35 isprovidedwith channel members 36 adapted to surround the guide rods I9 for vertical reciprocatory movement; The upper surface of thedriving block 35 has embedded therein a loop, 31 to which is adapted to be secured an eye 36 at the extremity of a lift cable 31' which extends over the pulley 24 and is looped, as at 38, about a U-shaped extension 39 secured, as by bolts 40, to the power lift arms I5. Suitable operating pedals 4| are provided for operating the power lift.

As best shown in Figure 4, guide means for the post to be driven are also provided and take the form of collars 42 slidable on the guide rods I9 and secured together, as by means of an arcuate flange 43. Suitable eyes 44 and 44' on the collars 42 support respectively a chain 45 and a clasp 46 adapted to surround the post to be driven and hold the same securely in position for driving.

From the foregoing the operation of the device should now be readily understandable. When it is desired to drive posts, as for example for a new fence, the tractor is simply run down the fence line and when the desired position for driving a post is reached, the post is placed between the guides I9 and secured in position, as by the chain 45 and the clasp 46, and the power lifting device energized through the operation of one of the pedals 4| to move the extending arm 39 to the position disclosed in full lines in Figure 2. This movement through the cable 31' raises the driving block 35 to its uppermost position. When the power lift is released, the block, which in the preferred embodiment of the invention may weigh approximately 250 pounds, is released and falls striking the top of the post. The preferred height of the vertical guide memhers I9 may lie in the neighborhaod: of. ten; ta twelve feet, and accordingly, it will be readily understood that a relatively heavy impact is de:- livered to the post to drive the same.. Under normal operating conditions, and dependent upon the condition of the soil into-which the; post is driven, it has been found. that half a dozen repeated strokes are usually suflicient to drive a post to a sufficient depth to secureiyhold; a fence. The tractor i then driven to the nextpost site andtheoperatiorr-isrepeatedi Obviously"; when itis desired to replace: posts in arr. existing fence? the tractor' may: bereadily backed? up toanydesired position, and the post driven in the manner" previously described;

From the foregoing; it' will now'be' seenthat there is herein provided a device accomplishing all"the= objects ofthi'sinvention; and others;- including-many advantages of great practical utility and commercial i importance;

Asmany embodiments may-be made of this inventive concept; and as many modifications may be madein the embodiment hereinbefore shown and" described-i it is 'to' be underst'ood that all matter herein is tube interpreted merely: as, i'llustratlvevand not lira-limiting sense:
